ChronoZonedDateTime getChronology() method in Java with Examples

The getChronology() method of ChronoZonedDateTime interface in Java gets the chronology of this date, which is the ISO calendar system.

Syntax:

default IsoChronology getChronology()

Parameter: This method does not accept any parameter.

Return Value: It returns the ISO chronology and not null.

Below programs illustrate the get() method:

Program 1:

// Java program to demonstrate 
// ChronoZonedDateTime.get() method 

import java.time.*; 

import java.time.chrono.*; 

import java.time.temporal.ChronoField; 

public class GFG { 

    public static void main(String[] args) 

    { 

        // create a ChronoZonedDateTime object 

        ChronoZonedDateTime zonedDT 

            = ZonedDateTime.parse( 

                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); 

        // print result 

        System.out.println("Chronology: "

                           + zonedDT.getChronology()); 

    } 
}

Output:

Chronology: ISO

Program 2:

// Java program to demonstrate 
// ChronoZonedDateTime.get() method 

import java.time.*; 

import java.time.chrono.*; 

import java.time.temporal.ChronoField; 

public class GFG { 

    public static void main(String[] args) 

    { 

        // create a ChronoZonedDateTime object 

        ChronoZonedDateTime zonedDT 

            = ZonedDateTime.parse( 

                "2018-10-25T23:12:31.123+02:00[Europe/Paris]"); 

        System.out.println("Chronology: "

                           + zonedDT.getChronology()); 

    } 
}
